Recently, many WMS(Web Map Services) and POI(Point of Interest) services come to be in service on the Internet using Web GIS(Geographic Information System) as Information Technology and computer H/W are evolved faster in its speed, network bandwidth and features. The Web GIS is, however, limited and constrained on the specification of its system configuration, the service class provided and the presentation methodology of a map. As the mobile Internet becomes popular in mobile service, Web GIS service on mobile environment is strongly required and to be provided by location based WMS(Web Map Service) on a mobile client such as PDA with location information of the user. In this paper, we made an effort to design and implement a GIS computing environment by thin client for mobile web map service. For implementing the thin client GIS computing environment. we were using NGII's(National Geographic Information Institute's) DXF map, representing the map by SVG(Scalable Vector Graphics) recommended by OGC(OpenGis Consortium), and adapting standard XML web service to provide the thin client GIS service on PDA by applying the location information of the user in realtime with GPS on mobile environment.

In recent years, speedy development of Taiwan's hotel industry intensifies market competition, customers' demands on hotel services quality also increase with the increase of their consumption consciousness, and their demands on hotel types diversify, therefore hotel industry should concern on their unique management services quality brought by their different hotel types. The current designed service system or service transmission process may fail to meet customers' demands owing to emphasizing degree gap in service quality. What is worse, it is difficult for hotel industry to actualize complete customer segregation and to provide customized services, therefore comprehensive understanding of customers' demands on the service quality of different types hotels would contribute to operating management improvement of Taiwan hotel industry. This paper divides Taiwan hotels into three types: international tourism commercial type, holiday type and motel, the general hotels. It studies the emphasize degree gap in service quality between the industry and the customers. Data analysis shows that service quality gap (perceived gap) of hotels of different types exists in several quality aspects; what's more, the perceived gaps, service quality aspects, and its items of different types of hotel are also different. After an integrated analysis, this paper puts forward a general and customer-oriented quality item suitable for hotel industry to shorten the perceived gap of service quality, so that the hotel industry could design a service system and service transfer system, which could meet most lodging customers' demands in the context of pluralized customer sources.

For the power system to keep in a stable operating state, sufficient ancillary services must be available to respond to credible contingency events and return the power system to a satisfactory operating state in the case of contingencies as well as blackout events within specified predefined limits. The logical and reasonable bases of valuing and pricing the ancillary services are required to reach the common ground among market participants. The total amount of black start service transactions is quite small compared to the total ancillary service transactions as well as energy market transactions. Black start services must be provided as one of the ancillary services in the deregulated electricity market. In order to procure and remunerate black start services, it is necessary to quantify the value of the black start sources within the power system. In this paper, an approach to assess the value of the black start service is presented based on the cost-of-service solution. Financial simulation of the influence on market participants for the proposed approach on the service is carried out. The cost of the black start service is allocated in accordance with the principle of "causer pays", and the cost is shared by the producers and consumers equally that created the requirement for the service. Under the present electricity market, the mechanism to recover the cost is not implemented, a new approach to the ancillary services to provide incentive for the service providers has to be studied in the near future.

With rapid expansion of the water market and growth of water companies, the recent trends in international water industry show that standardization of service activities concerning management of water and wastewater system (ISO/TC 224, to be issued in the second half year of 2007) is expected to have a large influence on the global water market including liberalization of water service market. In the Draft International Standard(DIS) of ISO/TC224, Performance Indicators(PIs) are suggested to estimate the service activities relating to water and wastewater treatment facilities. PIs have been developed in many countries including some international organization(World Bank, IWA and etc.) for service benchmarking. To evaluate public service level and establish plans to improve service level of wastewater utilities, we developed PIs for 120 items and applied them to 10 sewage utilities in the consideration of their scales, circumstances and conditions. In this study, we verified the applicability of the developed performance indicators(PIs). So, we concluded that PIs developed for the purpose of this study can be a useful tool applicable to objective evaluation of the service level of sewage utilities. Using the evaluation tool of PIs developed, it can also be used as a benchmarking tool in this industry as well as for enhancing the efficiency of operation and management of the sewage system. It will also contribute to the water resource management through determination of investment priorities based on the evaluation results and to raising international competitiveness of the domestic sewage utilities to meet the future opening of the water market.

Although a mobile Internet telephony service becomes popular with the rapid propagation of smart phones, its service quality management system has not been prepared enough yet. For successful settlement and deployment of the mobile Internet telephony service in future, a strict service quality management is required. The service quality management using a specific measurement equipment has limitations that real-time monitoring is impossible. In this paper, therefore, we propose a proactive service quality management system for the mobile Internet telephony service and develop a software for its implementation. The developed software is verified by comparing the measurement results from the developed software to those from the softwares commonly used, and it is proved that the developed software is quite reliable.

A large amount of food waste in known to bring about many problems including environmental pollution. This study was carried out to investigate effective methods for reducing leftovers in the food service business & industry. The reasons for producing leftovers in food service restaurants, customers perferences of foods, cooking methods the degree of saltiness, and serving size were surveyed using questionnaire and the menu was improved based on the customers perferences. Excessively large serving sizes and the unfavorable cooking methods is food service were the main reason for the leftovers of side dish and one=dish foods. Because the largest amount of leftover came from soups & stews, an effective way of reducing leftovers in food service would be to reduce the serving size of soups & stews. Total leftovers was reduced to about 60% after improving menu (p<0.01) and the each leftover or rice, soup&stew, and side dishes was also reduced significantly after improving the menu(p<0.001) The environmental campaign to reduced food waste by bulletin intra-net using personal computers slogans& posters, and new letters was conducted for one week each and then leftovers were measured 9 times for following three weeks regularly. The total amount of leftovers decreased slightly due to the environmental campaign, but the difference was not significant . When we adopted penalty or prize system leftovers were decreased by about 35%(p<0.001) and the penalty system was more effective than the prize system in reducing leftover (p<0.001) When we compared the leftovers under the three services, a tray service was more effective in reducing leftover than complete self-service of partial self-service(p<0.001).
